[問題] SSE與opencv2.1的問題

[wang71 (jack)]

各位大大, 想請教目前opencv2.1和sse的關係

小弟在一篇文章上提到

OpenCV was released on 6th May. This time the development team did not
release pre-built library for MinGW. They only released that for MSVC . There
was only one pre-built release library uploaded by other user but SSEs were
disabled.

然後小弟在網路上下載這個檔案OpenCV-2.1.0-win32-vs2008.exe
的確像opencv1.0一樣,直接安裝就可以用了
但是執行程式時,效能卻沒有提昇

所以想說,應該是這個版本的程式庫並沒有enable sse library.
然後目前使用cmake和opencv2.1.0去重新compile
但是卻沒有發現enable sse的選項
所以想請教各位大大,如何enable Opencv裡面的sse指令集呢

謝謝大大指教

推 wa120:在cvinternal.h裡 預設enable
→ wang71:謝謝大大的指教~~我有加入__SSE2__去
→ wang71:compile了,可是好像還是沒有變快的跡象>"<
推 wa120:在Visual C++底下 灰色代表disable XD
→ wa120:#if defined __SSE__ || MSC_VER >1300
→ wa120:                    ^^ 這是OR
